The irony here being that it wasn't even Dutch's brute force that saved him but his intelligence. Yes being strong helped him set up the traps but he was NOT even able to beat up the predator in a fist fight.
Someone like Arnold was not even able to hurt the predator with his own fists. It took the use of his brain to finally defeat him. that could have been any of the guys in Dutch squad.
That was EXACTLY the problem, the reason everyone died. They were all trying to kill the predator with guns and pure force. they relied on their guns. Dutch was finally able to rely on his brain and won.
it wasn't even because Dutch was the most badass.
Harrigan Saw things that no one saw, clues that no one cared about. He saw between the lines. he was the most clever person in his department. The one that realized there was something else going on, something weird.
If you think about it like that, about Their BRAINS, Harrigan makes perfect sense. if it wasn't for him no one would know it was the predator killing. Everyone thought it was just a guy killing
